A teaser video promoting Pink Floyd's forthcoming "Immersion Edition" box set edition of their classic 1979 album 'The Wall' has been posted online. Due Feb. 28, the seven-disc 'Wall' super-deluxe collection follows in the footsteps of the comprehensive 'Dark Side of the Moon' and 'Wish You Were Here' box sets, and, in addition to the remastered version of the original album, will feature a generous helping of demo tracks, live clips, a DVD with live footage from the original 'Wall' tour, and much, much more.

The 15-minute promo video for the "Immersion Edition" of 'The Wall' offers sneak peak audio excerpts of demos from several tracks off the album, including 'The Doctor' ('Comfortably Numb'), 'Another Brick In The Wall, Part 1,' 'Sexual Revolution,' 'Teacher, Teacher' and 'Outside The Wall.' It also has a handful of clips from 'Is There Anybody Out There: The Wall Live 1980-81,' which was digitally remastered for inclusion on the "Immersion" set.

Pink Floyd's 'The Wall' will also be available in a shorter three-disc "Experience Edition" and even a remastered vinyl edition. But the "Immersion Edition" is the one die-hard fans will want to get -- check out the complete track listing and inventory of bonus extras here.
